To be honest, your best bet might be to idle on alts for the skill training seals during this event and save those for the higher ranks. Otherwise as far as the actual skill goes, it's incredibly grindy and you might also want to utilize the complete skill exp pots (1 hour and 1 day durations) that come from the current event to get you more training (stacks with title). I forget if engineering gets a boost from life skill training potions but if it does that's another 2x too which stacks with the title and other potion.

If you're planning on grinding to 100 then stopping anyways, I'd recommend grinding to 99, then using a 500% exp fruit. Because of the weird exp chart discontinuity, you jump from lvl 99 to 109 or 110 depending on your current experience. From there it only takes a bit of exp to get to 110 if you're not 109, then you get 11 potential at lvl 110. TLDR, instead of reaching lvl 100, reach 99 then use a fruit.

Of course that only applies if you plan on stopping at lvl 100ish. It's still better to use it at higher levels than level 99 (just not in the early 100s).

Wow never knew about that kapra, guess this time around i'll try grinding to lvl 99 before i use those rb potions i have.

And yes, i've been idling away on my alts for the rewards. So at least i somewhat on track. I've also saved up at around 130 pts worth of training seals so that might help with the later lvls. And yes 4x training is incredibly helpful, yet the idea of making 200+ guns at rank 5 is still quite a daunting task.

And after trying to mine on floor 3 i notice a few things.

The top right side of the map is by far the easiest to clear then mine. There a mid size vein and 2 small ones. The huge one in the middle got patched a bit. I have seen ppl trying to edge into the corner from the right side and glitch into the back in a sense to mine. Now if you try to do that a few times you warp back to the front of the entrance.

Although it still possible to walk slowing to the edge and still mine the huge vein, but its much harder now.

Enthralling performance master + crisis escape are great if you want to mine but move the mobs away first. Killing mobs mean they respawn while you are drilling, moving mobs with the enthralling performance master title + crisis escape means they won't respawn on top of you without you being able to escape.

I just returned to Mabinogi too. Right now, they are selling 12th anniversary boxes here (CN Mabi) with enhanced skill training seals. I made a tough decision and paid to rank all those annoying skills with them.

They patched a lot of places, which is sad.

But the tips on the ores will help for future use, thanks for sharing.
